Mc Cool hat sein Klavier irgendwie über eine Midi-Kopplung zu einem Controller für die Xbox gelötet und spielt an diesem nun Tekken. Das klingt zwar eher so naja, aber er gewinnt.
This is the final product of my project for interaction design. Took the whole semester, to get this to work but it was worth it. How it works: The piano sends a Midi-Signal, which is transferred to an arduino. According to the signals, the arduino triggers transistors, which then trigger inputs on a paewang PCB (This is the PCB of an arcadestick). The paewang is connected to an Xbox360 (you can also use it on PS3).
